在 Rstudio 中，关闭文件选项卡时字符的编码会发生变化

Question

I have a code with Persian characters, like ( س ) in it. when I save the file, I get a warning: Not all of the characters could be encoded using ISO8859-1

when I close the file tab and reopen it again, the encodings have changed (turned into question marked). BUT , if I close the Rstudio ( without closing the file tab ), in reopening, characters are fine and unchanged.

saving with other encodings like utf-8 code didn't help.

any idea why this is happening and what should I do?

Answer 1

save with encoding cp1256 and reopen with encoding (same cp1256) solved it
